- Laser measurement point marker and large optics for exact measurement even at greater distances
- Fast recording of measurement values at two measurements per second
- Adjustable emissivity
- Two adjustable alarm limit values
- Good handling thanks to ergonomic „pistol design“
- Hold function and display of min./max. values
The testo 830 is a universally applicable infrared thermometer for non-contact measurement of surface temperatures in trade and industry. Thanks to a new
processor, and therefore better resolution, even more precise measurements are now possible. Temperature can now be recorded to an accuracy of 0.1 °C. Thanks to the min./max. function, the limit values of the last measurement can be displayed and even better monitored.
The testo 830 infrared thermometer in brief: testo 830-T1 with 1-point laser measurement spot marking and 10:1 optics.
testo 830-T2 with 2-point laser measurement spot marking and 12:1 optics.
testo 830-T4 with 2-point laser measurement spot marking and 30:1 optics. This instrument measures the surface temperature even of smaller objects at a safe distance.
External temperature probes can be connected.
